New ester derivatives of alkoxybenzoyldeoxyfluorouridine of the general formula ##STR1## wherein R stands for an alkoxy group having 1 to 4 carbon atoms, m for 1 or 2, and n for 3 or 4 with the proviso that when m is 2, the adjacent two R's may be combined to form an alkylenedioxy group as a whole. These derivatives are prepared by acylating a 2'-deoxy-3',5'-di-O-alkylcarbonyl-5-fluorouridine with corresponding benzoyl halides and are useful as active ingredients for anti-tumor agents, especially for oral administration.
通用公式##STR1##中的新烷氧基苯甲酰脱氧氟尿嘧啶酯衍生物,其中R代表具有1至4个碳原子的烷氧基,m为1或2,n为3或4,但当m为2时,相邻的两个R可以结合形成整体的烷二氧基基团。这些衍生物通过用相应的苯甲酰卤化物酰化2'-脱氧-3',5'-二-O-烷基羰基-5-氟尿嘧啶制备,可用作抗肿瘤药物的活性成分,特别适用于口服给药。
